> How is the 5M scope? Build quality and performance in it's class would like to hear your reviews. Is the scope open source too? Not open source as far as I know. Have it only for a day, so I am not qualify to do a review as yet. Check up youtube, there are a few video there. Google it, already some reviews on it. Quick point: 1. The build is good (bought the assembled set). But I hope it is not like those 1 month life-time product. There was no such complaints on the net yet. 2. The various buttons and switches make operation it easy and fast. To me, this is important as compare to navigating around the on screen menu when I am using the tool. 3. It is smaller and lighter than it appears to be. About size of 2 pieces 2.5" external HD stack together. 4. Works off 2x18650 lithium battery. Yet to test out the battery life. 5. Basic, useable, and it has 1-shot mode 6. No case. Can't save to SD. If you can wait for several more months, the chance of another open source handheld scope (much higher sampling rate) materializing is quite high. You may get it through taobao, but paying is a big problem though.
